You have created an IP-IP tunnel which will traverse interface at-0/1/0 and you would like to make sure that the tunnel is operational.
Which operational-mode command should you use to verify that the IP-IP tunnel interface is up?

A GRE tunnel is established between two routers. When a user on one end sends traffic with a large packet size to a user on the remote end, the packet never arrives. However, the problem does not exist for smaller packets.
What is the problem?

An IP-IP tunnel must meet which two requirements to function correctly? (Choose two.)

Refer to the Exhibit.

You want traffic destined for the 66.142.1.0/24 network to traverse an IP-IP tunnel. You notice traffic being sent to any address in that subnet is not being received. Upon reviewing the output shown in the exhibit, what is the problem?

Which three statements are true about tunnels? (Choose three.)

You must create an IP-IP tunnel between two routers on your network. These two devices are separated by 10 hops. The tunnel appears to be established, but no traffic is traversing the tunnel.
What causes this behavior?

Which field of the IP header is modified on a payload packet when using GRE?

Which two statements are true of GRE? (Choose two.)

Router 2 is receiving two announcements of a route to 10.0.0.0/8. Router 2 learned one version of the route from ISP-2; this announcement of the route was received first. The second announcement of the route was received from Router 1 using IBGP.
What will Router 2 do with the routes shown in the exhibit?
